children() and text nodes

[vmx]

It would be nice if children() would also return text nodes. Of course the default behaviour shouldn't be changed. But what about an additional parameter you can set to "true" if you want text nodes to be returned, too. An additional check for every text node would be needed, as phantom nodes shouldn't be return though.

One possible solution:

jQuery.fn.childNodes = function() {
     return this.pushStack( jQuery.map( this, "jQuery.makeArray(a.childNodes)" ) );
};

Replying to john: Does this really need to be in core? a plugin to deal with those nasty textNodes is more to my liking. this code is still in testing, I will release as a plugin if you like.

jQuery.fn.span = function() {return this.wrap('<span/>').parent()};
jQuery.fn.split = function(re,f) {
	var text=[];
	this.each(function(){
		var tnp = this.parentNode;
		var splits = this.nodeValue.split(re);
		for (var i=0;i<splits.length;i++){
			var t = document.createTextNode(f ? f(splits[i]) : splits[i]);
			tnp.insertBefore(t,this);
			text.push(t);
		};
		tnp.removeChild(this);
	});
	return this.pushStack( text );
};
jQuery.fn.replace  = function(re,f) {
	var text=[], tNodes=false;
	this.each(function(){
		var $this = jQuery(this);
		if (this.nodeType == 3){
			tNodes=true;
			text.push(this.parentNode.insertBefore(document.createTextNode(this.nodeValue.replace(re,f)),this));
			this.parentNode.removeChild(this)
		}else{
			text.push($this.text($this.text().replace(re,f)))
		}
	});
	return this.pushStack(tNodes ? text : this);
};
jQuery.fn.textNodes = function() {
	var text=[];
	this.each(function(){
		var children =this.childNodes;
		for (var i = 0; i < children.length; i++){
			var child = children[i];
			if (child.nodeType == 3) text.push(child);
			}
	})
	return this.pushStack(text);
};

One possible solution: {{{ jQuery.fn.childNodes = function() { return this.pushStack( jQuery.map( this, "jQuery.makeArray(a.childNodes)" ) ); }; }}}
